Oyakata (親方 : おやかた), master, especially a sumo coach. The literal sense is of someone in loco parentis. Shihan (師範 : しはん), merely means chief instructor; unlike the titles above it is not related to grade. Shidōin (指導員:しどういん), intermediate instructor, also unrelated to grade. Shishō (師匠 : ししょう) is another title used for martial arts instructors. Zeki (関 : ぜき), literally “barrier”, used for sumo wrestlers in the top two divisions (sekitori). -- source link
